Quality Control

Our production of this acrylic copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against critical parameters including solids content, viscosity, pH, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flames. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
